Title: Universal attachment link
Inventor: FLUX PETER ROBERT
IPC: A62B35/00
Filed: 1995-05-31
Abstract: An attachment link (10) is disclosed which is used for attaching a load (not shown) to an elongate element such as a safety line (50). The link (10) is designed to be universally applicable to a wide variety of safety systems such as those in which an elongate safety element is supported on a series of rotary brackets that allow the passage of an attached load without detachment from the elongate element. The attachment link (10) comprises a substantially C-shaped straddling portion (20) having a pair of legs (30) depending therefrom. Each of the legs (30) is provided at its end remote from the straddling portion (20) with connecting means (40) adapted for engagement by a karabiner/hook. The legs (30) may be deformable to assist with attenuation of sudden loads. The straddling portion may be provided with friction reducing means to minimise the effects of friction between the elongate member and the attached load.

Inventor: YOKOSE MAMORU
IPC: C02F11/12
Filed: 1996-12-20
Abstract: The present invention provides a process for treating arsenic-containing waste water, comprising adding an oxidizing agent, if necessary, to arsenic-containing waste water to oxidize trivalent arsenic in the waste water into pentavalent arsenic; adding a calcium compound to adjust the pH to 12 or higher; separating it into solid and liquid (first solid/liquid separation); calcining the resulting sludge, while adding a ferric salt to the treated solution to adjust the pH to 6-9 after the solid/liquid separation; and separating it into solid and liquid (second solid/liquid separation).  According to the present invention, it is possible to remove arsenic from waste water efficiently to yield treated water satisfying various tolerance limits under various regulations, while the arsenic-containing sludge separated from the waste water can become harmless in subsequent continuous steps.

Title: Multivariable process control method and apparatus
Inventor: BERKOWITZ PETER N
IPC: G05B13/02
Filed: 1995-03-31
Abstract: On-line control of a process is achieved by feedforward computations of manipulated variables setpoints (SP) modified during each of frequent optimization cycles by feedback trim (84) determined by actual versus predicted effects of setpoints changes on the process controlled variables. Process, economic, contractual and equipment parameter values are continuously polled and collected and used to compute the optimal setpoints for the manipulated variables before the feedback trim (84) is applied. Drift factors (87) are added to the feedback trim (84) to provide on-line calibration of key  measuring instruments. Drifts in process performance (87) are updated on-line periodically through self-running routines (72, 85) computed as calibration factors for predictor (81) and control (71) equations based on rigorous process simulations and actual plant performance.

Title: Apparatus for axially displacing a downhole tool or a tubing string in a well bore
Inventor: HAYNES MICHAEL JONATHON
IPC: E21B33/04
Filed: 1997-11-27
Abstract: An apparatus  for  axially displacing a downhole tool or a tubing string in a well bore equipped with a wellhead,  the downhole tool being supported by a tubing string in the well which includes a telescoping joint to permit the axial displacement of the tool is described.  The apparatus includes a lifting mechanism such as a hydraulic cylinder or a mechanical jack which is connected to a lift rod string.   The lift rod string engages a latch point in the telescoping joint to support the weight of the tubing string and the downhole tool.   The apparatus permits the downhole tool to be displaced within a range constrained by the length of the telescoping joint.  The apparatus further preferably includes a motor for rotating the lift rod string to permit downhole packers or anchors to be released by rotational movement of the tubing string.   The apparatus also preferably includes support legs to bear a portion of the weight of a suspended tubing string in order to reduce tension on the wellhead components.   The advantage is  a simple, light weight, versatile lifting apparatus which is inexpensively manufactured and readily transported from one wellhead to another.

Title: Lightweight intervention system for use with horizontal tree with internal ball valve
Inventor: MORGAN MICHAEL GRAHAM
IPC: E21B33/035
Filed: 1996-06-21
Abstract: A lightweight intervention apparatus is described for use with a single bore intervention operation and which is suitable for use with a sub-sea horizontal tree with a tree cap and integral ball valve. The lightweight intervention apparatus is adapted to be coupled to the horizontal tree and that when so coupled the integral ball valve within the tree can be actuated via the intervention apparatus and cycled between an open and a closed position. The annulus line within the horizontal tree is adapted to be coupled through the lightweight intervention apparatus to a separate annulus line such that the annulus line is separate from the main bore to facilitate control of the annulus for certain well functions. A significant advantage of this arrangement is that the internal diameter of the main bore is not reduced in any way by apparatus or equipment for separating the annulus line from the main bore so that full bore diameter may be used. The lightweight intervention apparatus includes a horizontal tree connector for mating with the sub-sea horizontal tree, a structural outer housing coupled to the horizontal tree connector and in which is located a sub-sea test tree and an upper top quick connect/disconnect connector which includes a sub-sea test tree latch within a pre-loaded external type connector.

Inventor: DUPONT ERIC
IPC: A61P35/00
Filed: 1996-08-07
Abstract: The present invention relates to cartilage extracts and to a method of producing the same. Shark cartilage extracts having anti-angiogenic, antitumoral, anti-inflammatory and anti-collagenolytic activites have been obtained by an improved process. The process comprises the steps of obtaining a homogenate of cartilage in an aqueous solution, this homogenate being separated in a solid fraction (SOLID EXTRACT) and a liquid fraction which was further fractionated to obtain a LIQUID EXTRACT having molecules of a molecular weight comprised between 0 to 500 kDa. The composition of the liquid extract has then been investigated by different ways. Further fractionation of this extract led to the preliminary characterization of some of its active components. Due to the multiplicity of biological activities of the total liquid extract, it can be used for treating numerous diseases or conditions such as those having components selected from the group consisting of tumor proliferation, angiogenesis, inflammation and collagenolysis. Several cosmetic applications based on the capacity of the liquid extract to improve skin barrier function are also under the scope of this invention. These extracts have no offensive effect on normal body functions. Therefore, these shark cartilage extracts have a very promising therapeutic value. The process for the obtention of cartilage extracts is simple and efficient. The unexpectedly valuable products obtained by this process are therefore an indication of a new and non-obvious process.
